Here’s some more trouble with that: if startups only solve problems that scratch a personal itch, we end up with 20 chat apps, 10 food delivery services, 5 bicycle rentals, Uber for maids, mobile dog shampoo services, basically startups that solve problems for 20-something urban tech workers. As others mentioned, better to find other people totally not like you and figure out what problems they have to solve. They may be boring problems too, but maybe you’ll stumble onto a totally unaddressed niche.
